Automatic sprinkler EC-8 series

extended coverage

The Series EC-8 Extended Coverage Pendent Sprinklers are decorative glass bulb sprinklers designed for use in light hazard occupancies. They are intended for use in automatic sprinkler systems designed in accordance with standard installation rules (e.g., NFPA 13) for a maximum coverage area of 400 ft2 (37,2 m2), as compared to the maximum coverage area of 225 ft2 (20,6 m2) for standard coverage sprinklers used in light hazard occupancies. The recessed version of the EC-8, intended for use in areas with a finished ceiling, uses either the two-piece Style 30 or 40 Recessed Escutcheon. The Style 30 Recessed Escutcheon provides up to 1/2 in. (12,7 mm) of total adjustment from the flush pendent position, whereas, the Style 40 provides 3/4 in. (19,1 mm) of vertical adjustment from the flush pendent position. The adjustment provided by the Recessed Escutcheons reduces the accuracy to which the fixed pipe drops to the sprinklers must be cut. Corrosion resistant coatings, where applicable, are utilized to extend the life of copper alloy sprinklers beyond that which would otherwise be obtained when exposed to corrosive atmospheres. Although corrosion resistant coated sprinklers have passed the standard corrosion tests of the applicable approval agencies, the testing is not representative of all possible corrosive atmospheres. Consequently, it is recommended that the end user be consulted with respect to the suitability of these corrosion resistant coatings for any given corrosive environment.
